Note: Be sure to subscribe to the newsletter and browse the archives. Headed by Roger Sessions, one of the world's leading experts in distributed object technology, "ObjectWatch offers several services to help make distributed objects work for you." Sessions is an advocate of COM+ and Microsoft's DNA architecture.

"Welcome to MTSense, your middleware link to all the best, free, hype-free, expert information on Microsoft middleware/transactional technologies..." Very slow, but lots of good info. Also see ComponentFocus, which discusses COM+, EJB and Corba.

Similar to Roger Sessions' ObjectWatch, this is a newsletter about COM+ and related topics, by David S. Platt, author of several Microsoft Press books about COM and COM+. He has a newsletter called Thunderclap, which is nearly on par with the ObjectWatch newsletter.
